[0030] A pressure rod 5 is provided on the top of the inner frame 3, and a ring frame 6 is fixed at the bottom of the outer side of the pressure rod 5, and the outer side of the ring frame 6 is in contact with the inner wall of the inner frame 3. A collection tube 7 is provided on the inner side of the side plate 4, and an adjustment component is sleeved on the outer side of the collection tube 7, and a slide groove 8 corresponding to the adjustment component is provided on the inner side of the side plate 4. The adjustment component drives the collection tube 7 to enter the inner side of the inner frame 3. The top end of the pressure rod 5 is transmission-connected to the output end of the cylinder 9, and the cylinder 9 is installed at the center of the bottom surface of the body 1. The pressure rod 5 uses the adjustment component to make the collection tube 7 move downward on the inner side of the inner frame 3, and the bottom surface of the inner frame 3 is provided with a through hole 10 corresponding to the collection tube 7. After the bottom end of the collection tube 7 passes through the through hole 10, the bottom end of the collection tube 7 is correspondingly plugged into the inner side of the soil to complete the collection of the soil. The adjusting component drives the collection tube 7 to move to the inner side of the inner frame 3, the cylinder 9 works, the pressure rod 5 at the output end of the cylinder 9 moves downward on the inner side of the inner frame 3, and the downwardly moved pressure rod 5 drives the collection tube 7 to move downward on the inner side of the inner frame 3 until the bottom end of the collection tube 7 is correspondingly plugged into the soil through the through hole 10, and the collection tube 7 is used to collect and process the soil at the collection position. Multiple adjusting components correspond to multiple collection tubes 7 one by one, and different collection tubes 7 can be conveniently moved to the inner side of the inner frame 3 by using the adjusting components, so that different collection tubes 7 can collect and process the soil at different collection positions, thereby ensuring the diversity and speed of soil collection.

[0031] exist Figures 2 to 5In the figure, an electric roller 11 is sleeved on the surface of the connecting rod, and the electric roller 11 is electrically connected to the controller, and the controller controls the flight of the body 1 and the rotation of the electric roller 11, and the electric roller 11 is connected to the power supply of the body 1, and a plurality of teeth 12 are fixed to the bottom of the outer side of the circumference of the electric roller 11, and a plurality of U-shaped frames 13 are arranged at the top opening of the inner frame 3, and the plurality of U-shaped frames 13 correspond to the plurality of side panels 4 one by one, and the movable adjustment component moves from the slide groove 8 to the inner side of the U-shaped frame 13, and an arc plate 14 is fixed on the top of the U-shaped frame 13, and a rack 15 is arranged on the top of the side panel 4, and the rack 15 surrounds the electric roller 11 and the outer side of the arc plate 14, and the rotating electric roller 11 drives the rack 15 to slide on the outer side of the arc plate 14, and the movable rack 15 drives the collection tube 7 to move by the adjustment component. The top of the inner side surface of the rack 15 is set flat. When the electric roller 11 rotates, the arc plate 14 and the electric roller 11 cooperate to limit the rack 15. The rotating electric roller 11 uses a plurality of teeth 12 to drive the rack 15 to rotate. The rotating rack 15 uses the flat position to slide on the outer side surface of the arc plate 14 to ensure the smooth rotation of the rack 15 and avoid excessive friction loss between the tooth grooves on the inner side of the rack 15 and the outer side surface of the arc plate 14.

[0032] The adjustment component includes a sleeve 16, and the collection tube 7 is vertically inserted into the inner side of the sleeve 16. A screw 17 penetrating the rack 15 is fixed to the top of the outer side of the sleeve 16. The outer end of the screw 17 is spirally sleeved with a nut 18. The nut 18 is located outside the rack 15, and the spiral cooperation between the nut 18 and the screw 17 enables the rack 15 to drive the sleeve 16 and the collection tube 7 to move synchronously. Both sides of the arc plate 14 are provided with grooves corresponding to the screw 17. The sleeve 16 is correspondingly inserted into the inside of the slide groove 8 of the side plate 4, and the bottom surface of the sleeve 16 is in contact with the inner bottom surface of the slide groove 8. At this time, the screw 17 on the outer side of the sleeve 16 passes through the rack 15, and the nut 18 is spirally sleeved on the outer end of the screw 17. At this time, the rack 15 and the sleeve 16 are connected.

[0033] When the rack 15 drives the sleeve frame 16 to move inside the slide groove 8 by means of the screw 17, the sleeve frame 16 drives the collection tube 7 to move synchronously, until the outer circumferential surface of the sleeve frame 16 fits the inner surface of the arc plate 14, and the bottom end of the collection tube 7 corresponds to the through hole 10. At this time, the screw 17 is inside the groove of the arc plate 14, so as to prevent the screw 17 from directly impacting the arc plate 14. The controller controls different electric rollers 11 to rotate, and can move the collection tubes 7 on different side plates 4 to the inner side of the inner frame 3, so that the entire collection device can collect soil at different positions and detect the moisture of the collected soil.

[0034] exist Figures 5 to 8In the figure, the adjustment component also includes a pressure plate 19, the bottom end of the pressure rod 5 corresponds to the top surface of the pressure plate 19, the outer circumferential surface of the sleeve frame 16 is provided with a side groove corresponding to the pressure plate 19, and limiting plates 20 are fixed on both sides of the side groove. The inner end of the pressure plate 19 is between the two limiting plates 20, and the inner end of the pressure plate 19 is in contact with the outer circumferential surface of the collection tube 7. A slider 21 is provided at the inner end of the pressure plate 19, and a wedge block 22 is fixed at the inner end of the slider 21. The outer circumferential surface of the collection tube 7 is provided with an annular groove 23, and the wedge block 22 at the inner end of the slider 21 is correspondingly clamped on the inner side of the annular groove 23. After the collection tube 7 is correspondingly inserted into the inner side of the sleeve frame 16, the outer circumferential surface of the collection tube 7 fits with the inner wall of the sleeve frame 16, and the bottom surface of the collection tube 7 is flush with the bottom surface of the sleeve frame 16. At this time, the wedge block 22 at the inner end of the slider 21 is correspondingly inserted into the inner side of the annular groove 23 of the collection tube 7. Since the bottom surface of the wedge block 22 is horizontally arranged and the inner bottom surface of the annular groove 23 is horizontal, the slider 21 can use the wedge block 22 to drive the collection tube 7 to move downward, ensuring that the collection tube 7 moves vertically downward inside the sleeve frame 16 to avoid the collection tube 7 from shifting.

[0035] When the sleeve frame 16 is on the inner side of the U-shaped frame 13, the pressure plate 19 is at the bottom of the pressure rod 5. When the pressure rod 5 moves downward, the downward pressure rod 5 drives the pressure plate 19 to move downward between the two limiting plates 20. Since the inner end of the slider 21 uses the wedge block 22 to correspond to the annular groove 23, the downward pressure plate 19 drives the collection tube 7 to move downward on the inner side of the sleeve frame 16 using the slider 21, and the bottom end of the downward collection tube 7 collects and processes the soil at the collection position through the through hole 10.

[0036] exist Figure 7 and Figure 8 In the embodiment, the inner end of the pressing plate 19 is provided with a slot corresponding to the slider 21, and a spring 24 is provided inside the slot, one end of the spring 24 is connected to the inner side of the slot, and the other end of the spring 24 is connected to the outer side of the slider 21, and a notch is provided on the top of the slider 21. The collected soil is inside the collection tube 7, and when the notch is used to pull the slider 21 away from the collection tube 7, the slider 21 cooperates with the spring 24 inside the slot to squeeze the moving slider 21 to move the wedge 22 out of the inner side of the annular groove 23, so that the collection tube 7 carrying the soil can be pulled out from the inner side of the sleeve frame 16, so that the new collection tube 7 can be plugged into the inner side of the sleeve frame 16.

[0037] Side blocks 25 are fixed on both sides of the slider 21, and inner grooves 26 corresponding to the side blocks 25 are arranged on both sides of the slot. The moving slider 21 slides inside the inner groove 26 by means of the side blocks 25, and the length of the inner groove 26 is less than the length of the slot. When the bottom surface of the collection tube 7 is flush with the bottom surface of the sleeve frame 16, the wedge block 22 corresponds to the annular groove 23 of the collection tube 7, and the elastic force of the spring 24 makes the slider 21 slide inside the slot of the pressing plate 19. When the moving slider 21 drives the wedge block 22 to approach the collection tube 7, the inner groove 26 cooperates with the side blocks 25 to prevent the slider 21 from deviating or detaching from the pressing plate 19 during the sliding process, until the slider 21 cooperates with the wedge block 22 to limit the collection tube 7.

[0038] exist Figure 5 and Figure 8 In the figure, side tubes 27 are fixed on both sides of the inner end of the pressing plate 19, and the two side tubes 27 correspond to the two limiting plates 20 one by one. A plug rod 28 is screwed in the center of the side tube 27, and the inner end of the plug rod 28 is tightly fitted with the surface of the side block 25. A spring bar 29 is arranged at the center of the limiting plate 20, and the top of the spring bar 29 is connected to the side tube 27. The downward pressing plate 19 uses the side tube 27 to squeeze the spring bar 29. When the slider 21 clamps the collection tube 7 with the wedge block 22, the side block 25 corresponds to the side tube 27, and the plug rod 28 is screwed in the inner side of the side tube 27. The inner end of the plug rod 28 that screws through the side tube 27 is tightly pressed against the outer side of the side block 25. The pressure of the plug rod 28 is used to improve the stability of the collection tube 7 inside the sleeve frame 16 through the slider 21.

[0039] When the pressure rod 5 drives the collection tube 7 downward by using the pressure plate 19, the downwardly moving pressure plate 19 uses the side tube 27 to squeeze the elastic strip 29 on the surface of the limiting plate 20 until the collection tube 7 collects the soil at the collection position. Then, the output end of the cylinder 9 drives the pressure rod 5 upward, and the elastic force of the elastic strip 29 causes the side tube 27 to drive the pressure plate 19 to drive the collection tube 7 to move upward synchronously until the bottom surface of the collection tube 7 is flush with the bottom surface of the sleeve frame 16. Then, the electric roller 11 drives the rack 15 to rotate in the opposite direction. The rack 15 that rotates in the opposite direction drives the collection tube 7 to move back to the inner side of the chute 8 of the side plate 4 by using the adjusting component. At this time, the inner bottom surface of the chute 8 corresponds to the bottom opening of the collection tube 7 to prevent the soil from falling out of the inner side of the collection tube 7 during the flight of the body 1. In addition, the multiple side plates 4 facilitate the distinction of the soil collected by the collection tube 7 to prevent the collected soil from being mixed.

[0040] Working principle of the present invention:

[0041] Reference Figures 1 to 8As shown, the sleeve frame 16 is correspondingly inserted into the inside of the slide groove 8 of the side plate 4, and the bottom surface of the sleeve frame 16 is in contact with the inner bottom surface of the slide groove 8. At this time, the screw 17 on the outer side of the circumference of the sleeve frame 16 corresponds to the rack 15, and the nut 18 is spirally sleeved on the outer end of the screw 17. At this time, the rack 15 and the sleeve frame 16 are connected, and the body 1 uses the inclined frame 2 to drive the collection component to move until the body 1 moves to the collection position. The controller controls the electric roller 11, and the rotating electric roller 11 uses a plurality of teeth 12 to drive the rack 15 to rotate. The rotating rack 15 uses the flat position to slide on the outer side of the arc plate 14 to ensure the stability of the rotation of the rack 15.

[0042] When the rack 15 drives the sleeve 16 to move inside the slide groove 8 by means of the screw 17, the sleeve 16 drives the collection tube 7 to move synchronously, until the outer circumferential surface of the sleeve 16 fits with the inner surface of the arc plate 14, and the bottom end of the collection tube 7 corresponds to the through hole 10. At this time, the screw 17 is inside the groove of the arc plate 14, so as to prevent the screw 17 from directly impacting the arc plate 14. When the wedge block 22 on the inner side of the slider 21 is clamped with the collection tube 7 by the elastic force of the spring 24, the side block 25 corresponds to the side tube 27, and the insertion rod 28 is screwed inside the side tube 27. The inner end of the insertion rod 28 that screws through the side tube 27 is tightly pressed against the outer side of the side block 25. The stability of the collection tube 7 inside the sleeve 16 is improved through the slider 21 by means of the pressure of the insertion rod 28.

[0043] When the sleeve frame 16 is on the inner side of the U-shaped frame 13, the pressure plate 19 is at the bottom of the pressure rod 5. When the pressure rod 5 moves downward, the downward pressure rod 5 drives the pressure plate 19 to move downward between the two limiting plates 20. Since the inner end of the slider 21 uses the wedge block 22 to correspond to the annular groove 23, the downward pressure plate 19 drives the collection tube 7 to move downward on the inner side of the sleeve frame 16 using the slider 21, and the bottom end of the downward collection tube 7 collects and processes the soil at the collection position through the through hole 10.

[0044] When the pressure rod 5 drives the collection tube 7 downward by using the pressure plate 19, the downwardly moving pressure plate 19 uses the side tube 27 to squeeze the elastic strip 29 on the surface of the limiting plate 20 until the collection tube 7 collects the soil at the collection position. Then, the output end of the cylinder 9 drives the pressure rod 5 upward, and the elastic force of the elastic strip 29 causes the side tube 27 to drive the pressure plate 19 to drive the collection tube 7 to move upward synchronously until the bottom surface of the collection tube 7 is flush with the bottom surface of the sleeve frame 16. Then, the electric roller 11 drives the rack 15 to rotate in the opposite direction. The rack 15 that rotates in the opposite direction drives the collection tube 7 to move back to the inner side of the chute 8 of the side plate 4 by using the adjusting component. At this time, the inner bottom surface of the chute 8 corresponds to the bottom opening of the collection tube 7 to prevent the soil from falling out of the inner side of the collection tube 7 during the flight of the body 1. In addition, the multiple side plates 4 facilitate the distinction of the soil collected by the collection tube 7 to prevent the collected soil from being mixed.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
